all life on earth started as unicellular, prokaryotic organisms. which of these structures was vital for organisms to develop in order to evolve into more complex, multicellular organisms?\na nucleus\nb ribosomes\nc cytoplasm\nd cell membrane
Answer
Brief Explanations:
Prokaryotic organisms lack a nucleus. The development of a nucleus was crucial for the evolution of more complex, multicellular organisms as it allowed for better organization and regulation of genetic material. Ribosomes are for protein - synthesis, cytoplasm is the fluid inside the cell, and the cell membrane is for protection and transport, but the nucleus was key for complexity.
Answer:
A. nucleus
